Magnus Isaksson

Professor, vice-chancellor of strategic development, head of department

Research subject: Elektronik

Professor Magnus Isaksson received the M.Sc. degree in microwave engineering from the University of Gävle, Gävle, Sweden, in 2000, the Licentiate degree from Uppsala University, Uppsala, Sweden, in 2006, and the Ph.D. degree from the Royal Institute of Technology, Stockholm, Sweden, in 2007. In 2012 Dr Isaksson was appointed Docent in Telecommunications at the Royal Institute of Technology, Stockholm.

He worked on communication products with the Televerket, Sweden, during 1989—1999. He is a teacher in signal processing for Telecommunications and is currently the Head of the Department of electronics, mathematics, and natural sciences at the University of Gävle.

His main interests are in signal processing algorithms for radio-frequency measurements and modeling of nonlinear microwave systems.
